OTTO GRAG-OR KLEIN, OF PEORIA, ILLINOIS.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed April 9, 1909. Serial No. 488,854.

To all whom it may concern:

Be it known that I, O'r'ro GRAGOR KLEIN, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented a new and useful Clnn'n, of which the following is aspecification.

The invention relates to in'qprovcinents in churns.

The object of the present. invention is to improve the construction ofchurns, and to provide a simple, inexpensive and efficient one, capableof easy operation and adapted to quickly produce butter.

A further object of the invention is to provide a churn of thischaracter, having a plu "ality of reversely rotating dashers, adaptedalso of independent use to arrange the churn to suit differentconditions.

lVith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimhereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claim, may be resorted to with out departing from the spirit orsacrificing any of theadvantages of the invention.

In the drawing :Figure 1 is a vertical sectional view of a churn,constructed in accordance with this invention. Fig; 2 is a similar view,taken at right angles to Fig. 1.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

The churn comprises in its construction inner and outer reverselyrotating dashers 1 and 2. The inner dasher 1 consists of a vertical stemand horizontally disposed open rectangular blades 3, extending outwardlyfrom the stem at diametrically opposite points. The outer dasher 2consists of a rectangular frame and horizontally disposed openrectangular blades 4, extending inwardly from opposite sides of theframe and alternating with the blades of the inner dashcr. The frame ofthe outer dasher is of a size to receive the inner dasher, and thealternate arrangement of the horizontally disposed blades permit thereverse rotary movement of the dashers. The lower end of the stem of theinner dasher is arranged upon the upper face of the bottom of the frameof the outer dasher, and is provided with a bearing 5, and the saidouter dasher is also provided at the center of its bottom with a bearingopening (3, registering with the bearing 5 of the stem of the innerdasher and receiving a vertical journal 7, extending upward from thebottom of the churn body The ournal extends upward from a disk or head9, which provided with a threaded stem 10 embedded in the bottom of thechurn body. The journal connects and centers both of the dashers at thebottom of the churn body.

The churn body, which is supported by legs 11, may be of any desiredconstruction, and it is equipped with a suitable cover 12, upon which ismounted a bearing bracket. The bearing bracket consists of upper andlower sections or members 13 and l t. The lower section or member 1a iscomposed. of inclined sides anda horizontal top connecting portion, andthe upper member is constructed in a similar manner, its inclined sidesbeing secured to the outer faces of the sides of the lower section. Thehorizontal connecting portion of the upper section or member is arrangedin spaced relation with the top of the lower section or member toprovide an intervening space for the reception of an upper gear 15,having a depending hub extension 16 extending through a central bearingopening of the top connecting portion of the lower section or member 14of the bearing bracket. The hub extension and the upper gear areprovided with a rectangular opening, and the stem of the inner dasher isprovided with a reduced upper portion 17, squared at the top to conformto the configuration of the rectangular opening of the upper gear, butthe opening of the upper gear and the upper end of the reduced portionof the stem of the dasher may be of any other non-circular shape. Thelower end of the reduced portion is rounded and extends through abearing opening of a lower gear 18, having a depending hub extension orleaf 1%) provided with a squared lower portion 20, which fits in asquare openin 21 of the top of the outer dasher, whereby the latter isinterlocked with the lower gear, but the opening 21 and the engaginglower end 20 of the sleeve or hub extension 19 may be of any othernon-circular shape. The lower gear is also provided at its lower facewith a projecting annular flange 22, forming an extension of the lowerface of the gear and engaged by clips 23, secured to the upper face ofthe cover of the churn, whereby the lower gear is retained in place. Theupper portion of the depending hub extension or sleeve 19 is rounded andarranged in the central bearing opening of the cover of the churn body.

The upper and lower horizontal gears mesh with a vertical gear 24L,mounted on a horizontal shaft 25 and secured to the same by a set screw26, or other suitable means. The shaft is journaled in suitable bearingsin alined bearings of brackets 27, and it is equipped at its outer endwith an operating device preferably in the form of a wheel 28, having aneccentrically operated handle 29.

The reduced portion of the stem of the inner dasher detachablyengagesthe upper gear and may be readily withdrawn from the gearing whenit is desired to use the outer dasher only. The outer dasher isdetachable from the sleeve or hub extension of the lower gear, and whenthe dashers are removed from the churn body, they may be readilyseparated so that either or both may be connected with the gearing. Theouter dasher, which is equipped with the opposite blades, forms a doubledasher, while the inner dasher provides a single dasher construction.When both dashers are used a triple effect is produced through theopposite arrangement of the blades of the outer dasher and the centralarrangement of the blades of the inner dasher.

The cover or lid of the churn body is equipped with an opening 30,having a suitable closure 31 and adapted to permit water to be suppliedto the churn body without removing the dashers. The churn body is alsoprovided with a spout 32 and a drain opening 33, normally closed by aplug, or other suitable means, and in practice the churn body will beequipped with a transparent plate or pane to enable the operator toinspect the condition of the contents of the churn body. The lid may besecured on the body by hooks 3e and eyes 35, or any other suitablefastening devices, and a me tallic thimble 36 may be employed to preventthe lower end of the stem from wearing.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is z- A churn including a churn body havinga cover, an outer dasher provided at the top with a polygonal openingand having a bearing opening at the bottom, said outer dasher being alsoprovided at opposite sides with inwardly extending open rectangularblades, an inner dasher consisting of a stem provided at the lower endwith a bearing and having a reduced upper portion and removably arrangedwithin the outer dasher, the blades of said dasher being alternatelyarranged, a vertical pivot projecting from the bottom of the churn bodyand passing through the lower bearing opening of the outer dasher andextending into the bearing of the inner dasher, a lower gear arranged onthe cover of the churn body and having a hub extension passing throughthe cover and fitting in the opening of the outer dasher and detachablyinterlocked with the same, an upper gear detachably interlocked with thereduced portion of the stem of the inner dasher, and an operating shafthaving a vertical gear meshing with the upper and lower gears forrotating the said dashers.

In testimony, that I claim the foregoing as my own, I have heretoaflixed my signature in the presence of two witnesses.
